Bird Mode

The Bird mode sets up the radar for optimal detection of flocks of birds, which indi-
cates the presence of schools of fish. Additionally, the bird mode can be used to detect
distant rain clouds.
Gain, sea clutter and rain clutter are automatically adjusted according to the bird mode
setting.
The use of echo trail and echo average functions together with the bird mode make it
easier to distinguish bird echoes from other echoes. With echo average, echoes from
birds are emphasized. With true echo trails, moving vessels show long, steady trails.
Unlike those targets, bird echoes appear randomly and show random, short trails.
The bird mode has three settings according to the current level of sea clutter:
